Gerry Posted May 29, 2016 Share Posted May 29, 2016 What is the material, velvet, wool surge, bolton twill or what?Look up the particular fabric at http://www.whaleys-bradford.ltd.uk/CheersGerry Link to comment Share on other sites More sharing options...
numberwrong Posted May 29, 2016 Author Share Posted May 29, 2016 Thanks, useful site with G per m2 for each fabric. It'll be wool serge, I kind of knew this would be a 'how long's a piece of string question', I'll have to get the info from the draping company after bank holl, just fancied working out a rough load on a truss today :) Link to comment Share on other sites More sharing options...
ontoprigger Posted May 29, 2016 Share Posted May 29, 2016 It will also depend on who's material you use, wool serge comes in anything from about 290gsm to600 gsm.A good quality is going to be around 500gsm with something around 350 being ok for the more budget minded Link to comment Share on other sites More sharing options...
mac.calder Posted May 29, 2016 Share Posted May 29, 2016 And don't forget to multiply in your fullness if you are going for a pleated drape - it can more than double the weight of the drape. Link to comment Share on other sites More sharing options...
Jivemaster Posted May 29, 2016 Share Posted May 29, 2016 remember to account for any chain in the pocket at the bottom. If there is chain it's to add weight to make things hang well so it will not be plastic chain. Link to comment Share on other sites More sharing options...
numberwrong Posted May 30, 2016 Author Share Posted May 30, 2016 Thanks for the advise, I suppose the acid test is, how heavy is the whole drape you're flying, not worked out by a g per m2 formula, just the flying weight as specified by the supplier.
